Integrally suppressed bolt gun.

Ight, heres the deal im about to embark on a journey that I have been dreaming of for some time. The plan is an integrally suppressed 308. I want to keep overall barrel 16-20 in. Will be going 700 short action, whether that be bergara, or an older reworked rem action. Not sure on chasis or stock, but heavily leaning a nice dark american walnut. (classy) Now for the question, wbere are guys that have went this direction before, having the barrels made? Or if anyone has a "guy" that they know of. Thanks guys.
